3×3 terminal grid
Nine real shells in one window arranged in a tight grid. No tabs to hunt, no panel resizing.
macOS · Windows · single-keyboard parallel agents
Nine AI sessions.
One keyboard.
A drop-in VS Code build for the Claude Code / Codex / Gemini era. A 3×3 terminal grid, broadcast typing across panes, and one-click preset launchers — designed for running every agent at once instead of tab-switching between them.
Why nine?
One AI agent at a time leaves your CPU and your attention idle. Nine Agents runs nine concurrent terminals in a 3×3 grid, lets you type into all of them at once (broadcast), and ships a preset bar so every agent launches with a single click.
Built on VS Code's xterm.js — no ghost-frame artifacts that plague Zed-based terminals running Claude Code TUI.

vs Zed
Clean Claude Code TUI rendering — no DEC mode 2026 ghost frames.
vs Cursor
Run nine agents at once instead of one chat at a time. Your extensions stay.
vs stock VS Code
3×3 terminal grid, broadcast input, preset bar — all native, no extensions.
Built for the way you ship in 2026.
Broadcast input
Toggle once. Every keystroke and Enter goes to every pane — same prompt to Claude, Codex, and Gemini in parallel.
Preset launchers
Zed-style button row with usage counts and per-preset gear settings. One click and your favorite agent is running.
No ghost-frame artifacts
Powered by VS Code's xterm.js. Claude Code TUI renders cleanly — unlike alacritty-based editors missing DEC mode 2026.
Hidden editor chrome
Editor headers off, gutter 0, terminal noise filtered. Your screen is for code and conversation.
Still VS Code
Every extension, every keybinding, every theme. Nine Agents is a focused fork, not a rewrite.
One price. No subscription.

Independent developer, ships side-tools while running a startup. Nine Agents is the editor I use every day — building it because the existing options break under parallel AI workflows. Reply to any email and you'll get me, not a queue.
FAQ
Which platforms are supported?
macOS on Apple Silicon (M1+) and Windows x64. Intel Mac and Linux are on the roadmap — email us if you need them.
What exactly does the $39 license cover?
One device at a time, lifetime use of v1.x including all minor updates. Reassign by Help → Deactivate on the old machine — no support ticket needed. Source patch is closed, but the underlying microsoft/vscode is MIT and you keep your editor if the company disappears.
How does the one-time-download link work?
After payment you get a unique download URL. The first click starts a 60-minute window with resume support, so a flaky network won't strand you. If anything fails, your license key always re-issues a fresh link.
I lost the email or the download link. What now?
Open Nine Agents (or any browser) and use License → Re-send download — or email [email protected] with your license key. New link arrives in under a minute.
What if I switch laptops?
Help → Deactivate on the old machine, then enter the key on the new one. Or email us — we'll release the slot.
What about refunds?
30 days, no questions. We'd rather not have your money than your frustration.
Is Nine Agents open source?
It's a private fork of microsoft/vscode (MIT, full attribution shipped in the app). The grid / broadcast / preset layer is closed source for now.
